Do the anti-DST people understand what they're advocating for?
They do, which is why only 45 countries observe DST.
25 observe it partially.
And the rest, roughly ~125 countries do not.
Historically, ~140 countries did.
To put this into perspective, only about 1.2B people out of 8.3B observe it today. Which puts you into a very small <15% minority.
